Fish shrimp and crab feed pellet production method - SUNSHINE Industrial


To make fish, shrimp and crab feed pellets, it is generally necessary to go through the steps of batching, crushing, mixing, conditioning, puffing, granulation, drying, oil spraying, cooling and packaging.


First, weigh the various raw materials according to the feed formula, then crush and mix them, and then condition them to soften them. Then, use an extruder to expand the feed, and then granulate them to make pellets of the required size. Finally, dry, spray oil, cool and package the pellets to complete the production of feed pellets. 


Here are more detailed step-by-step instructions:


1. Batching:

According to the nutritional needs of fish, shrimp and crabs, select appropriate feed raw materials, such as fish meal, soybean meal, shrimp and crab processing by-products, yeast, vitamins, minerals, etc., and weigh the required weight ratio. 

2. Crushing:

Crush the weighed raw materials to make them into fine powder for subsequent mixing and digestion and absorption.

3. Mixing: 

Mix the various crushed raw materials to evenly distribute the various ingredients and ensure the nutritional balance of the feed. You can use a double-shaft paddle mixer and other equipment for mixing. 

4. Conditioning:

 Send the mixed feed powder into the conditioner, add an appropriate amount of water, and heat and stir to soften the feed powder to prepare for the subsequent puffing process. The temperature and time of conditioning need to be controlled according to the specific situation. 

5. Puffing: 

Send the conditioned feed into the puffing machine, and the feed will be puffed through the extrusion of the screw and the high temperature, increase the surface area of the feed, improve the digestibility, and make it easier to float in the water. 

6. Granulation: 

Extrude the puffed feed through different types of screens to make particles of different sizes to suit the specifications and feeding habits of different fish, shrimps and crabs. 

7. Drying: 

Dry the prepared feed pellets to remove excess moisture, prevent the feed from deteriorating, and increase its storage time.

8. Oil spraying:

 Spray a layer of fish oil or other oils on the surface of the dried feed pellets to increase the palatability and energy content of the feed. 

9. Cooling: 

Cool the feed pellets after oil spraying to reduce their temperature to a safe range for subsequent packaging and storage. 

10. Packaging: 

Pack the cooled feed pellets for easy transportation and sales. 


Raw material selection: Select fresh and high-quality raw materials to ensure the quality and safety of the feed. 


Formula design: Design a reasonable feed formula according to the growth stages and nutritional needs of different fish, shrimps and crabs to achieve the best feed utilization rate. 


Production process: Strictly control each link in the production process to ensure the quality and stability of the feed. 


Storage conditions: Store the feed pellets in a cool, dry and ventilated place, avoid direct sunlight and high temperature to prevent the feed from deteriorating.
